Marijuana has been a cash crop for many years in this country. The only problem is that most of that crop had been grown illegally. Now, that medical marijuana is legal in 15 states and the District of Columbia, legalized marijuana has quickly become so popular it is attracting attention from hedge fund managers and venture capitalists, not to mention a whole new batch of entrepreneurs.

Doctors still can’t prescribe marijuana because it is categorized as a schedule one drug like LSD. But they can recommend it and that’s all anyone needs to get a medical marijuana license that allows them to buy marijuana legally in those 15 states, with three more states about join them.

Each license sells for around $130 and some clinics selling the licenses have brought in more than a million dollars in just their first year. The once illegal joint is selling like hot cakes throughout middle America to consumers who no longer have to worry about getting arrested for possession, at least by local or state authorities.

The federal government still outlaws marijuana possession but it’s unlikely someone with a medical marijuana license will be busted by an FBI or DEA agent if caught smoking in his or her own home. In fact, just last year U.S. enforcers promised to leave medical marijuana operations alone if they complied with state law.

That prompted a significant increase in interest among entrepreneurs. Today, there are an estimated 2,400 medical marijuana dispensaries from California to Maine. In Colorado, they outnumber Starbucks two to one.

Credit card companies that prevented card-holders from donating money to the secrets outlet WikiLeaks could have their operating licenses taken away in Iceland, according to members of the Icelandic Parliamentary General Committee.

“People wanted to know on what legal grounds the ban was taken, but no one could answer it,” Robert Marshall, the chairman of the committee, said. “They said this decision was taken by foreign sources.”

The committee is seeking additional information from the credit card companies for proof that there was legal grounds for blocking the donations.

Marshall said the committee would seriously review the operating licenses of Visa and Mastercard in Iceland.

WikiLeaks’s payment processor, the Icelandic company DataCell ehf, said it would take immediate legal action against the companies to make donations possible again.

“DataCell who facilitates those payments towards Wikileaks has decided to take up immediate legal actions to make donations possible again,” DataCell CEO Andreas Fink said last week. “We can not believe WikiLeaks would even create scratch at the brand name of Visa.”

“It will probably hurt their brand much much more to block payments towards WikiLeaks than to have them occur,” Fink added.

Four Queens men claim they were locked up for more than 30 hours by cops seeking revenge on a crowd of men who laughed at an officer who couldn’t catch a fleeing drug suspect.

The men insist they didn’t even laugh, says their lawyer Gabriel P. Harvis, who filed suit against the NYPD and 10 unidentified officers in Brooklyn Federal Court. They believe they were arrested because cops wanted to take their frustration out on them, he said.

“The cops knew my clients had done nothing wrong, but they didn’t care,” said Harvis, who represents Abdul Kabba, Isaiah Barnes, Hasan Allen and Ishmial Deas. Police “were embarrassed, so they abused their power by locking them up anyway.”

The four were held for 27 hours in the 103rd Precinct stationhouse before the Queens district attorney’s office dropped the charges.

Smith told McClatchy news service: “It’s pretty clear that the medical marijuana industry is becoming recognized more and more by the mainstream as a fully legitimate part of the economy.”

Legalization “didn’t happen in 2010, but it’s likely to happen in 2012,” he added. “It’s going to be relatively soon we’re going to see states move from medical marijuana into broader legal markets. And the federal government needs to catch up. Frequently the American people are ahead of the Congress.”
